电热原子化原子吸收分析易受基体的干扰,使得准确度的提高受到限制.有关减少和消除这个影响已有报导。Czobik等人曾指出,为减少和消除基体的干扰,应设计一种具有时间和空间上等热条件的石墨炉。恒温石墨炉有上述的性质,用它作原子化器能消除和减少基体的影响。Hageman等人报导了用Woodriff炉作原子化器,基体对测定铅和锰的影响已被消除,认为在恒温石墨炉中不存在基体的干 Electrothermal atomization atomic absorption spectroscopy is susceptible to interference with the substrate, which limits the accuracy of the measurement, and reports on the reduction and elimination of this effect have been reported. Czobik et al. Have pointed out that in order to reduce and eliminate the interference of the matrix, a graphite furnace with time and space isothermal thermal conditions should be designed. Constant temperature graphite furnace has the above properties, use it as a atomizer can eliminate and reduce the impact of the substrate. Hageman et al. Reported that Woodriff furnaces were used as the atomizer. The influence of the matrix on the determination of lead and manganese was eliminated and it was assumed that there was no matrix dryness in the constant temperature graphite furnace
